Brian - what's the mess with intermixing cmd shell, and rebol one? 
See above output. And why do I need to hit enter to get back to rebol 
console?

R2 intermixed the cmd shell with CALL - with R3 you do that manually 
if you need to.
As for your other question, look at this:

>> call "cmd.exe /c dir"
== none

>>  Volume in drive E is APPS
 Volume Serial Number is 7845-7730

 Directory of E:\REBOL\2.100

               7 Dir(s)   4,893,769,728 bytes free

I did that 1 + 1 to show that I didn't have to hit enter to get back 
to REBOL. You only have to hit enter to see the prompt. The extra 
>> above the dir outpt is the result prompt that you aren't seeing 
below. This is because CALL on Windows returns immediately, rather 
than waiting for the called process to finish its work, including 
its console output.
Keep in mind that this behavior may change in the future: CALL is 
in the host code.

how do I trap the console output into the variable for e.g.? something 
like str: call "cmd /c dir" does not make it ...
Henrik
15-Aug-2009
[16752]
call/output "cmd /c dir" my-var

I think
Pekr

[16753]
there is no refinement with R3 call :-)
Henrik
15-Aug-2009
[16754]
well, I guess in R3 you don't do that. :-) Forget my response.
Pekr
15-Aug-2009
[16755]
the only chance, probably, is to catch console port?
Henrik
15-Aug-2009
[16756]
does 'echo work?
Pekr
15-Aug-2009
[16757x2]
Call is pretty unusable with R3. I have to say, that some ppl could 
already move to R3, but we have few showstoppers:

- call - really bad situation ....
- missing networking protocol 
- missing CGI mode

- DB access ... now we can proceed with extensions for SQLite, but 
not sure. If call would work at least, we could at least call sqlite.exe 
;-)


Unless those issues are fixed, R3 will be in alpha stage, and my 
opinion is - absolutly unnecessarily ...
echo? who want to work with file? Theat is weird. I want call being 
fixed, or it is good for nothing ...
Henrik
15-Aug-2009
[16759]
I thought you wanted debug output. Otherwise wait until CALL is fixed.

Pekr, what are yhou trying to do?
Sounds like Pekr is trying to capture the output of a directory listing 
in R3, is that correct?
anyway Pekr, just use:

call "cmd dir > somefile.txt"

then you can just read the file back into a string.
Pekr
15-Aug-2009
[16763x2]
Paul - correct ....
Paul - I know that is an option ... but what is it good then to get 
'call output into console, if it can't be even easily captured into 
a string?
Paul
15-Aug-2009
[16765]
Isn't that a limitation of R3?
Pekr
15-Aug-2009
[16766]
dunno. As an interim solution, you suggestion is good enough .... 
I'll wait for 'call being fixed/enhanced ...
Paul
15-Aug-2009
[16767]
Yeah, we will have to wait and see if they develop 'call further.
BrianH

CALL is in the host code. We'll fix it when the host code is released.

Can anyone tell me how to view an image with r3?

Is it me, or the example to read a dns address is broken ???

Geez...

>> first wait read dns://www.rebol.net
read
== 216.240.11.203

>> first wait read dns://216.240.11.203
read
== "www.rebol.net"

A little bit obfuscated, but it works...

Nicolas, VIEW in its built in state doesn't work properly, so do 
something like this:

>> load-gui
>> a: load http://arkandis.com/images/blog/google.gif
>> b: make gob! [image: a]
>> view b

I see Carl is going to add Read/Text functionality with UTF conversion. 
 That is going to be sweet.  That alone should begin to make REBOL3 
useful.

What is the point of /any on dir?

As far as I can see, as soon as you add a wildcard char, dir?/any 
always returns true

    dir?/any %ddddff.file
    == false                              ;; no wild ==> false
    dir?/any %ddd?dff.file
    == true                                ;; wild ==> true
    dir?/any %ddd*dff.file
    == true                               ;; wild ==> true

    dir?/any http://www.test.com/file.html
    == false                             ;; no wild ==> false
    dir?/any http://www.test.com/*.html
    == true                              ;; wild: true

It's already there - add your code as a comment on the existing DIR? 
/any ticket.
The ticket in question is #649.

I proposed change of command! to external! extern! or something like 
that. We will see, if Carl reacts to that ....
BrianH
18-Aug-2009
[16785]
The word "command" is more specific, and better expresses what you 
are referring to.
Pekr
18-Aug-2009
[16786]
I have heard at least one other opinion, that name "command" might 
be too worthy to waste on simple and signle thing as wrapping merely 
a funciton call. Of course even Devices have commands, but those 
are not probably rebol level related and influence nothing ...
BrianH
18-Aug-2009
[16787x2]
You mentioned that "command" would need to be reserved for devices. 
There's no reason that devices couldn't use the existing command! 
type. It's very flexible.
Carl said that devices would be a variant on extensions.
Pekr
18-Aug-2009
[16789x2]
No, I said, that device commands probably don't influence rebol level 
code, so that we are eventually free to rename extension command 
to extension! term. That was just a thought, in case we would have 
some better usage for 'command term later. Nothing really important 
imo. Extension commands are not much advanced - they are just descriptor 
for particular meaning.
When I think "command", I think - dialect ...
BrianH

[16791]
Sorry, I wrote that in relation to what you had said on the blog, 
not here.
Pekr
18-Aug-2009
[16792]
and to just describe meaning of wrapping a call, I though external!, 
extern!, ext!, wrap! could be used instead. Probably too late to 
try to convince anyone :-)
BrianH

[16793]
Those are all modifier words. We need a noun.
Pekr
18-Aug-2009
[16794x2]
more interesting stuff on Chat :-) I expressed opinion, that we use 
assymetry for read and write with strings, Carl objected. His second 
post might be interesting for you, as he for few moments thought, 
where is the right place for such stuff. I think that you would enjoy 
putting your opinion there. Of course - my post was done just to 
provoke some discussion :-)
btw - "external", english-wise, can't be thought as a noun?
BrianH
18-Aug-2009
[16796]
I just read it, and was about to reply to your counter-post, just 
to one point.
External

 is an adjective. When used as a noun, its subject is implied. Bad 
 form.
